IMPROVEMENT IN REGISTERS.

Specification forming part of Letters Patent No. 180, 165, dated July25, 1876; application filed {November 23, 1874.

To all whom it may concern:

Be it known that I, JOHN A. STENBE-RG, of Chicago, in the county of Cookand State of Illinois, have invented certain Improvements in Registersfor Meters, 850., of which the following is a specification Thisinvention relates to numerical registers or indicators, to be applied tometers or to any other apparatus where the registration or indication ofrevolutions or vibrations is required.

In this invention I employ a series of circular disks, which formcog-wheels, and each of which is provided with a pinion, which pinionforms itself the shaft upon which both pinion and disk turn, obviatingthe necessity for a separate shaft, and the whole series is so arrangedthat the pinion of the first disk engages the periphery of the next, andso on, as in a diminishing train of gearwheels, each remove lesseningthe motion. Each disk is marked upon its face with the Arabic numerals,and constitutes a revolving dial.

The series are brought nearly into a single plane by inclining all ofthe axes or shafts, and overlie or overlap each other like the scales ofa fish. This forms a very simple and compact register.

Motion is imparted to the right-hand disk and diminishes in proper ratiotoward the left, so that by reading along a guide-line from left toright the true amount indicated may be read as ordinary figures placedin a line, the first disk at the right indicating units, the secondtens, the third hundreds, and so on, the teeth upon peripheries andpinions being apportioned so that they shall move in this ratio to eachother, as will be understood from the following description and theaccompanying drawing, which forms a part of this specification, and inwhich drawlug- Figure l is a face view of the register with the casingremoved, and Fig. 2 a longitudinal central section of casing andregister.

In the said drawing, A A A A A A A represent the series of overlappingtoothed disks, each carried upon an inclined shaft, 1), and furnishedwith a pinion, c, the shaft being formed by the extension downward ofthe pinion. This enables me to make pinions in large quantities bysimply drawing a metal wire through a suitable-shaped apertureto give itthe proper form, the same being cut to proper lengths and applied to thedisks. This greatly cheapens and simplifies the manufacture.

The right-hand or units disk, A I prefer to tooth ratchet fashion, as itreceives the power, and I find it more convenient to convert the motionto be registered into a vilratory motion and impart it to the units-diskby means of a double pawl, as shown in the drawing, and as will bepresently described. The remaining disks and all of the pinions aresimple cog-gears.

The disks, being geared together, move, of course, alternately inopposite directions. The numerals from 0 to 9 are, therefore, arrangeddifferently upon each alternate disk, increasing in the direction of therotation, which is indicated at Fig. l by the arrows below the disk.

Upon the glass cover 61 is marked a median line, the position of whichis indicated in Fig. 1 by the dotted line 0 6. This serves as aguide-line in reading the register. The same result would be effected bya slit in the metal cover, or a row of holes; but I prefer a line uponthe glass. In case a metal cover is used, the shafts b may extend up toit fora bearing.

The ordinary and well known rule for reading continuous-motion registersis observed in this invention-that is to say, the lesser numeral nearestthe line is read the same as in dials where a moving pointer isemployed, in which the lesser numeral nearest the pointer or index isread to the exclusion of others.

In this case, owing to the arrangement of the disks, the entire amountregistered may be read at a glance from left to right in natural order.

It will be seen that, by inclining the shafts and disks to the plane ofthe reading-line, I am enabled to greatly condense the mechanism andreduce it to a compact form, the disks themselves forming the dials.

Motion is imparted to disk A by means of the spring liftingpawl f, whilea check-pawl, g,- prevents any return. The pawl f may communicate withthe apparatus the motion ions, the bearings or shafts of which consistof which is to be registered. of the elongated pinions projecting; intoa base- Baving thus fully described the construcplate, as described andshown.
